Constructor and Description
ShortPointer()
ShortPointer(int size) Allocates a native short array of the given size.
ShortPointer(Pointer p)
ShortPointer(short... array) Allocates enough memory for the array and copies it.
ShortPointer(ShortBuffer buffer) For direct buffers, calls Pointer.Pointer(Buffer), while for buffers backed with an array, allocates enough memory for the array and copies it.

Constructor Detail

ShortPointer

public ShortPointer(short... array)

Allocates enough memory for the array and copies it.

Parameters:

array - the array to copy

See Also:

put(short[])

ShortPointer

public ShortPointer(ShortBuffer buffer)

For direct buffers, calls Pointer.Pointer(Buffer), while for buffers backed with an array, allocates enough memory for the array and copies it.

Parameters:

buffer - the Buffer to reference or copy

See Also:

put(short[])

ShortPointer

public ShortPointer(int size)

Allocates a native short array of the given size.

Parameters:

size - the number of short elements to allocate

ShortPointer

public ShortPointer()

See Also:

Pointer.Pointer()

ShortPointer

public ShortPointer(Pointer p)

See Also:

Pointer.Pointer(Pointer)

Method Detail

allocateArray

private void allocateArray(int size)

position

public ShortPointer position(int position)

Description copied from class: Pointer

Sets the position and returns this. That makes the array.position(i) statement sort of equivalent to the array[i] statement in C++.

Overrides:

position in class Pointer

Parameters:

position - the new position

Returns:

this

See Also:

Pointer.position(int)

limit

public ShortPointer limit(int limit)

Description copied from class: Pointer

Sets the limit and returns this. Used to limit the size of an operation on this object.

Overrides:

limit in class Pointer

Parameters:

limit - the new limit

Returns:

this

See Also:

Pointer.limit(int)

capacity

public ShortPointer capacity(int capacity)

Description copied from class: Pointer

Sets the capacity and returns this. Should not be called more than once after allocation.

Overrides:

capacity in class Pointer

Parameters:

capacity - the new capacity

Returns:

this

See Also:

Pointer.capacity(int)

get

public short get()

Returns:

get(0)

get

public short get(int i)

Returns:

the i-th short value of a native array

put

public ShortPointer put(short s)

Returns:

put(0, s)

put

public ShortPointer put(int i,
               short s)

Copies the short value to the i-th element of a native array.

Parameters:

i - the index into the array

s - the short value to copy

Returns:

this

get

public ShortPointer get(short[] array)

Returns:

get(array, 0, array.length)

put

public ShortPointer put(short... array)

Returns:

put(array, 0, array.length)

get

public ShortPointer get(short[] array,
               int offset,
               int length)

Reads a portion of the native array into a Java array.

Parameters:

array - the array to write to

offset - the offset into the array where to start writing

length - the length of data to read and write

Returns:

this

put

public ShortPointer put(short[] array,
               int offset,
               int length)

Writes a portion of a Java array into the native array.

Parameters:

array - the array to read from

offset - the offset into the array where to start reading

length - the length of data to read and write

Returns:

this

asBuffer

public final ShortBuffer asBuffer()

Description copied from class: Pointer

Same as Pointer.asByteBuffer(), but can be overridden to return subclasses of Buffer.

Overrides:

asBuffer in class Pointer

Returns:

asByteBuffer().asShortBuffer()

BytePointer.asBuffer(), asBuffer(), IntPointer.asBuffer(), LongPointer.asBuffer(), FloatPointer.asBuffer(), DoublePointer.asBuffer(), CharPointer.asBuffer()
